Redundant Auto Land System for Predators
By Cyndi Wegerbauer (*)
San Diego, California -- July 6 -- General Atomics Aeronautical Systems, Inc. (GAÊ‰79;ASI), a leading manufacturer of unmanned aircraft surveillance systems, has integrated and tested the UAV Common Automatic Recovery System (UCARS) into the U.S. Air Force Predator® UAV. The system has been tested extensively in over 400 automatic recoveries during System Integration Lab (SIL) simulation and actual flight tests. UCARS provides the Predator with the ability to make a completely automatic approach, touch down, roll out and stop on a runway. This same capability can be used for automatic takeoff.
UCARS Launch & Recovery Profile
As a parallel effort, GA-ASI has developed and flight tested a Differential GPS system that provides automatic takeoff, approach and landing using Differential GPS. The auto land Human Machine Interface (HMI) is common between UCARS and DGPS auto land systems, providing a dual redundant system. If the systems deviate in approach parameters that exceed a predetermined threshold, the aircraft is programmed to execute a missed approach and automatically initiate a new approach. This dual redundant system, using both UCARS and DGPS, provides a greater degree of safety and reliability during all weather conditions, including zero visibility.
A company spokesman said, "The redundancy approach of incorporating two different auto takeoff and land systems into the Predators adds a dimension of required safety that cannot be achieved with a single technology based system." This same auto takeoff and land capability will be offered in export Predators and the jet powered Predator B's.
